RSI high/low [experiment]

This is an experiment.

This is a RSI based on candle high / low instead of close.
If the candle is up / green then the high is used.
If the candle is down / red then the low is used.

Feel free to ask if you have any question.

- Now using the native RSI function
- Fixed an error in the code caused by doji candles
